Abstract: <P>PROBLEM TO BE SOLVED: To provide a method being smoothly driven by decreasing frictional resistance between a pile and the ground by a device for pulling out the unnecessary pile in the ground.  <P>SOLUTION: A copper pipe 12 with a short length is welded to the front end of a sheet pile 11, the copper pipe 12 having an inside diameter slightly larger than an outside diameter of the pile to be pulled out, and it is piled on the sheet pile 11 to weld. The copper pipe 12 is so mounted that the frictional resistance between the pile 1 and the ground is decreased. A water supply pipe 13 is mounted to the inside of the sheet pile 11. Since a closing part F surrounded by the sheet pile 11 and the pile 1 can be loosened by jetting high pressure water from a jet nozzle on the front end of the water supply pipe 13, as a result, a pull-out device 10 can be smoothly driven. Since the copper pipe can be driven in the ground by the time not longer than a half in comparison with a method 20 using the conventional copper pipe by using the sheet pipe 11, the method is very efficient and economical.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
